Your GH being zero is not a good sign. Is Ca and Mg provided my MS? I have to be honest, I only skimmed through the MS articles and am still at the point of mineralizing, and I'm using the premix kit, so I'm not sure. If not, you should look into adding some GH booster.
The scape looks pretty good to me, just needs to fill in. The only thing out of place to me are the rocks on the right, they form too much of a wall and should be set a bit more naturally. The ones on the left are pretty symmetrically placed, also, maybe pull a few together and move in or out to add some depth there.
